Problems solved by technology
[0005] However, in the existing technology, the display panel is usually used as the 3D light valve at present, and the color resistance is removed, or another screen is directly made, but because the light of the display panel needs to pass through the polarizer, the light transmittance of the 3D printed display panel LCD Only about 5%, it requires more energy from the UV light source, and the printing efficiency is low

Abstract
The invention discloses an electrowetting display panel and a 3D printing system. The electrowetting display panel comprises a first substrate and a substrate base plate which is oppositely arranged,the electrowetting display panel further comprises a plurality of data lines and a plurality of gate lines, and the data lines and the gate lines are insulated and crossed to define a plurality of pixel units; wherein each pixel unit comprises a shading layer and a first electrode layer which are sequentially formed on a first substrate, and the shading layer comprises a first opening part; a driving circuit layer comprises a third opening part, and the orthographic projection of the third opening part and the orthographic projection of the first opening part in a plane where the first substrate is located are overlapped; a hydrophobic layer comprises a second opening part, and the orthographic projection of the second opening part and the orthographic projection of the first opening parton the plane where the first substrate is located are not overlapped; micro-droplets are included between the first electrode layer and a second electrode layer, the micro-droplets are gathered aftera voltage signal is applied to the first electrode layer and the second electrode layer, and the orthographic projections of the micro-droplets and the second opening part on the plane where the firstsubstrate is located are overlapped. The electrowetting display panel and the 3D printing system provided by the invention have the characteristics of high transmittance and high contrast.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to an electrowetting display panel and a 3D printing system. Background technique [0002] Rapid prototyping technology (also known as rapid prototyping manufacturing technology, Rapid Prototyping Manufacturing, referred to as RPM), also known as 3D printing, is a high-tech manufacturing technology based on the material accumulation method. The method of accumulating materials can produce a physical object or a physical model. Due to the advantages of greatly reducing production costs, improving the utilization of raw materials and energy, customizing according to needs, and greatly saving product production time, 3D printing technology has gradually entered the public eye and developed rapidly in recent years. [0003] 3D printing is a new rapid prototyping manufacturing technology. It manufactures products through the principle of multi-layer superposition growt...
